The Col loque of our European Institute for social security to prepare the Conference in the Hague on the social security and the economic crisis was held from the 17th ti 11 the 19th of September in Toledo. Part II of the Yearbook 1980-1981 contains the reports presented in Toledo. The reports are focussed on the over- a! 1 economic situation (Richard Draperie); the specific problems of Pensions (Bernd Schulte); the cost of medical care (Leo Crijns); unemployment insurance (Joachim Volz); the social minimum (Andre Laurent) and two special reports on the economic crisis and social security. Finally it contains my own synthesis report. Al 1 the participants had the opinion that the colloque created a fruitful 1 basis for a further in depth discussion in the Hague in 1982. The Institute once again wants to express its sincere gratitude to Antonio Chozas and his colleques for the excellent and adequate way in which they organised the colloque.
